New research shows permafrost below shallow Arctic lakes is thawing as a result of changing winter climate.

In contrast, the warming on the land may increase the protective vegetation layer and delay thawing of permafrost outside of lakes,» said Vladimir Romanovsky of the UAF Geophysical Institute and co-author of the new study.

That would allow lake water to soak into thawed soil, but Carroll is not aware of any evidence that the permafrost in the far north is melting yet.

Found in the Arctic and cold mountain regions, thermokarst lakes occur as permafrost thaws and creates surface depressions that fill with melted freshwater, converting what was previously frozen land into lakes.

Countering a widely - held view that thawing permafrost accelerates atmospheric warming, a study published this week in the scientific journal Nature suggests arctic thermokarst lakes are «net climate coolers» when observed over longer, millennial, time scales.

The study also revealed another major factor of this process: Researchers found that when the lakes drain, previously thawed organic - rich lake sediments refreeze.

They found that high rates of carbon accumulation in lake sediments were stimulated by several factors, including «thermokarst erosion and deposition of terrestrial organic matter, -LSB-...] nutrient release from thawing permafrost that stimulated lake productivity, and by slow decomposition in cold, anoxic lake bottoms.»

«Thawing permafrost is already releasing significant masses of largely inorganic mercury to lakes and the Arctic Ocean,» wrote the authors of a 2011 study from Canada's Freshwater Institute.

Other eDNA data — in this case from lake sediments — are illuminating how the postglacial thaw transformed other landscapes too, such as temperate forests.

Northern Siberia: As lakes in the permafrost zone of northern Siberia thaw, they are releasing methane — a potent greenhouse gas.

«Thawing permafrost causing the «browning» of northern lakes: Increase in terrestrial organic matter in northern lakes.»

Carbon in the form of rotted plants is stored in coal, the mud of oceans and lakes, and soil, but the rotted - plant carbon in permanently frozen ground is both abundant and easily released once carbon - laden permafrost has thawed.

Their findings, published March 9 in Proceedings of the National Academy of Sciences, show that groundwater from the seasonal thawing of the «active layer» of soil above the permafrost adds significantly to the overall concentration of methane in the lake and thus influences the emission of this powerful greenhouse gas to the atmosphere.

According to research published in the journal Science («Disappearing Arctic Lakes,» June 2005), thawing permafrost may explain the shrinking or disappearance of hundreds of large Arctic lakes across western SibLakes,» June 2005), thawing permafrost may explain the shrinking or disappearance of hundreds of large Arctic lakes across western Siblakes across western Siberia.

The idea here is that rising air and soil temperatures thaw permafrost, allowing the lakes to drain away into the ground.

Permafrost thaw in the Arctic can initially lead to wetter landscapes, development of new lakes and wetlands, and increased CH4 emissions [Olefeldt et al., 2016].

That is organic material spread all across the Arctic lands, which thaws as the permafrost thaws, and rises through multitudes of lakes and bogs as methane.

What I should mention about my trip, which took place in mid-June 2017, is that while I thought that would be ample time for ice and snow to thaw and reveal perfect blue lakes and 100 % accessible hikes, I was sorely mistaken.
